For the following scenarios, please tell me what the minimum sample size needed is, rounded up to the nearest integer (e.g., if your answer is 51.3, round it up to 52). Remember that you cannot survey a fraction of a person – it has to be a whole person. If you round down, then you won’t have the minimum amount of precision needed, so you must round up. For the z-scores, refer to table provided Confidence Level z-score 90% 1.65...
